Reader extensions

This egg installs a reader extension for #\@ that reads a date/time literal as described below in read-date-literal. Additionally, a record printer is installed so that all SRFI-19 date objects are automatically printed using write-date-literal.

Note that there are some caveats to using reader extensions when compiling; for more details, refer to the relevant FAQ entry.

Input and output

read-date-literal

[procedure] (read-date-literal [PORT])

Reads a date/time literal from PORT, which defaults to the value of (current-input-port). The literal is converted to an SRFI-19 date using the first matching format template as follows:

#@~Y-~m-~dT~H:~M:~S~z

#@~Y-~m-~dT~H:~M:~S

#@~Y-~m-~d

write-date-literal

[procedure] (write-date-literal DATE [PORT])

Writes the SRFI-19 date object DATE in #@~Y-~m-~dT~H:~M:~S~z format to PORT, which defaults to the value of (current-output-port).
